HEADLIGHT.

Specification of Letters Patent.

Patented July 29,

Application filed September 27, 1912. Serial No. 722,595.

T 0 all whom it may concern:

Be it known that I, Rnmnom H. lVArrmza, a citizen of the United St ates, residing in the. borough of ll'lanhattan, city, county, and State of New York, have inven ed an Improvement in Headlights, of which the following is a specification.

My invention relates to that class'of head lights employed by physicians in making examinations of the cavities of the mouth, eyes and the like, and also by scientists in making various examinations in research worlg.

llcretofore these instruments have generally been constructed so as to fit over the head of the examiner, and have been pro vidcd with a concave mirror and a source of light. \Vith these. instruments, however, ditl'iculty has been experienced in obtaining an even diffusing of the light directed innncdiately upon the object under examination, and the purpose of my invention is the provision of such an instrument. in which a circle of light. isobtaiucd, in which the li 'ht is evenly distributed over the entire circle.

ln carrying out this invention, and in ol) taiuing the objects sought, I employ togcthcr with the concave mirror and the source of light a comparatively small condensing lens, by which the cmicentrated rays from the source of light are reflected upon the object. being examined, which may be placed at a variable distance t'roui the. mirror, depending of course upon the. position of the condensing lens.

In the drawing, l igure 1 is a perspective view of my improvcd head light. Fig. 2 is a plan view of the parts of the same, and Fig. 3 is an enlarged cross section on line :I' a, Fig. '12.

Referring to the drawing, my improved head light. preferably comprises a band 10 made. olany suitable material and constructed so as to be. adjustable to lit around the head of the examiner by whom the in strumcnt. is used. in a suitable. position, a plate ii is secured to the band it). This plate. U is provided with a stud ll, the. outer or free end of which is spherical, as indicatcd at til. I also employ a frame ll proforably comprising parallel bar members if), bctwccn the sockets in one end of which the spherical head 11 of the stud .12 hi 16 dcsignates a concave. mirror tixed in a suitable tramc l7, from the hack of which extends a stud 1S.

Similarly to the stud iii the stud 1S terminates at its free end in a spherical head 19 which tits within sockets provided therefor in the opposite ends of the bars 15. By this structure, as will be understood, the mirror 16 is adjusta able to substantially any position.

Connected to the mirror trains J is a tube 20," one portion of which of reduced cross section, as is indicated at 21. Connected to the tube 20 is a terminal means of which, through a suitable sochet,

electrical connections may he made to from the instrument. Th so (.(71llll"l.lill'l--; however, form no part of this in veution, a d for this l'ltlSUl'l not, illustrated in the drawing.

The reduced portion turned on itself, and at. fitted with a socket- 23, adapted tale-xii small electric lamp 3+, Fitted a soclvet i3 and adjustable lo it thereon, I employ a slcevelii, a2 the free end of the tube is a coat lens so. As will be apparent, the (,i; mirror reflects the rays of light from lamp at the point of greatest. concentration, and a. circle of evenly distriiml d light in o tained at. a variable distance tron the mirror, depending upon the relative positions anally .ot the lamp and. the condensing lens.

l claim as my invention:

1. A. head light comprisine' an ad} band, a source of light, a frame ditch the same is secured, a mirror secured to l n; said frame in' a lined position relatively t (c the said source of light, means for lftins'itr traling the. rays' of light from the st. thereof on the said mirror, and me: adjustaldy connecting the mirror to lac band.

l. A head light; comprising an aclju band, :li,} 9lt ."[lltf lamp, a trame in which the said lamp-is secured, a. concave mirror cured to the said frame. in a lixed position relatively to the said lamp, a devi e able to position relatively to the for comrcntrating the. rays of light. from on the said mirror, and nice justahlv connecting the. mirror to i band.

25. A. head light comija'ising an a band, an electric lamp, :1 frame in oi v c oi which the. electric lamp ser ated,

said min s! in {he said band.
